1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

objectivesThe common practice is to remove symptomatic common bile duct (CBD) stones in patients. This study aimed to investigate the factors affecting the percutaneous transhepatic removal of CBD stones.

methodsWe retrospectively analyzed the data of 100 patients (66 men and 34 women; age: 25-105 years, mean 79.1 years) with symptomatic CBD stones who underwent percutaneous transhepatic stone removal (PTSR) from January 2010 through October 2019. After balloon dilation of the ampulla of Vater or bilioenteric anastomosis, the stones were pushed out of the CBD into the small bowel with a balloon catheter. If failed, basket lithotripsy was performed. Technical success was defined as complete clearance of the bile ducts on a cholangiogram.

resultsThe technical success rate was 83%, and achieved 90.2% in patients with altered gastroduodenal/pancreatobiliary anatomy. Multivariable analysis revealed that CBD diameter (odds ratio [OR]: 506.460, p = 0.015), failed ERCP (OR: 16.509, p = 0.004), Tokyo guidelines TG18/TG13 severity (grade III; OR: 60.467, p = 0.006), and left-sided transhepatic approach (OR: 21.621, p = 0.012) were risk factors for technical failure. The appropriate cutoff CBD size was 15.5 mm (area under the curve: 0.91). CBD stone size, radiopacity of stones, and CBD angle between retroduodenal and pancreatic portion did not influence technical success.

conclusionsPTSR is effective for CBD stone removal in older adults and individuals with altered gastrointestinal tract anatomy. The aforementioned risk factors for technical failure should be considered in preoperative evaluation before PTSR to improve the success rate. KEY POINTS: • PTSR is effective in symptomatic CBD stone management among older adults and individuals with altered anatomy. Investigating clinical /anatomic factors can guide radiologists toward a more comprehensive preoperative evaluation to maximize the success rate. • Our data indicate that dilated CBD (diameter ≥ 15.5 mm) and left-sided PTBDs reduce the technical success rate by 506-fold and 22-fold, respectively. • Clinical factors such as previous failed ERCP for stone removal and higher severity of acute cholangitis lessen the technical success rate.
